Quaternary dynamic differential logic with application to fuzzy-logic circuits
This paper introduces a new dynamic quaternary CMOS technique. Using only standard enhancement MOSFETs with no threshold modifications was one aim of the development. The difference between two successive logical voltages has to be greater than the threshold voltages of the MOSFETs. Thereby, a high noise margin can be reached. The paper shows dynamic circuits for connecting the quaternary circuits with binary ones. Furthermore, quaternary OR- and AND-gates are given. In connection with literal-operators, all quaternary logic functions can be realized with the technique introduced. In addition, four Fuzzy-logic circuits are shown, namely a bounded-sum and a bounded-difference circuit as well as a drastic-product and a drastic-sum circuit.
